Patient Name: Avery Brook Chief Complaint (CC): "Slipping grades and
Age / Gender: 10 Years Old / Female daytime fatigue"
Height: 4’7” (140 cm) Encounter Specialty: Pediatric Advanced
Weight: 80.0 lbs (36.4 kg) [75th Percentile] Assessment
Level of Difficulty: Advanced Pathophysiology &
DDx
Setting: Outpatient Pediatric Clinic
1. Executive Case Summary
Avery Brook is a 10-year-old female brought to the outpatient pediatric clinic by her mother due to a 3-to-4
month history of declining academic performance, chronic daytime lethargy, mild progressive weight gain
despite reported poor appetite, and general social withdrawal at school. Her mother notes that Avery
previously earned straight A's in 4th grade but has recently received C's and D's in her 5th-grade class. The
teacher reported that Avery appears "foggy," frequently stares off into space, moves slowly, and occasionally
falls asleep during quiet reading periods.
Initial differential diagnostic considerations spanned neurodevelopmental disorders (Attention-
Deficit/Hyperactivity Disorder, Inattentive Type), primary sleep disorders (Pediatric Obstructive Sleep Apnea
due to adenotonsillar hypertrophy), psychiatric conditions (Pediatric Major Depressive Disorder), and
metabolic/endocrine disorders (Acquired Juvenile Hypothyroidism, Type 1 Diabetes Mellitus, or Chronic
Anemia). Upon structured history and thorough physical evaluation, key pertinent negatives were identified:
absence of hyperactivity, lack of night terrors or snoring, no overt sad mood or self-harm ideation, and lack
of polyuria or polydipsia. Pertinent positive physical findings included mild diffuse non-tender goiter, dry
cool skin, delayed relaxation phase of deep tendon reflexes (bradyreflexia), and mild periorbital edema.
2. Primary Learning Objectives
Pediatric Diagnostic Reasoning: Distinguish between primary neurodevelopmental/cognitive disorders
and underlying systemic/endocrine etiologies presenting as academic decline in school-aged children.
Comprehensive Pediatric History: Demonstrate mastery of structured pediatric interviewing techniques
using HPI frameworks (OLD-CARTS) and multi-system Review of Systems (ROS).
Physical Exam Skills: Accurately identify clinical signs of pediatric thyroid dysgenesis/dysfunction, including
thyroid gland palpation, cutaneous manifestations, and deep tendon reflex kinetics.
Lab Interpretation & Evidence-Based Management: Interpret pediatric thyroid panels (TSH, Free T4, Anti-
TPO antibodies), formulate evidence-based Levothyroxine dosing, and design a multi-disciplinary follow-up
and monitoring plan.
